A simulation system having multiple peripherals that communicate with each other. The system includes a weighted graph with weights set as communication times. The peripherals are represented as nodes and connection paths are represented as edges. Among the communication times in the loop, the minimum time is set as first synchronization timing. Timing with an acceptable delay added is set as second synchronization timing. Timing set by a user to be longer than the first and second timings is set as third synchronization timing. The third synchronization timing is used in a portion where the timing is usable, thus synchronizing the peripherals at the longest possible synchronization timing.

Simulation method, system and program

A system acquires an output program for sequentially executing a plurality of character string output instructions, and thereby for outputting a text in which a plurality of output character strings are combined. The system converts the character code set of the character string constants, which is outputted by at least one of the character string output instructions, from a first code set for internal processing to a second code set for output, before the output program is executed. In addition, the system buffers the values of two or more character string variables to be outputted by two or more of the character string output instructions without converting the character code set from the first code set, during the execution of the output program.

Method for optimizing character string output processing

A program editing apparatus includes a user interface control unit, a JSP analysis unit, and a split execution unit. The user interface control unit accepts an input of a split object instruction which specifies a portion to be split off from a JSP file to be processed. The JSP analysis unit determines an accompanying split portion which is split off together with the portion specified by the split object instruction. The split execution unit splits off the portion specified by the split object instruction and the accompanying split portion from the original JSP file. The JSP analysis unit analyzes dependence of variables and objects in the JSP file and splits off a copyable portion by copying. Thus, a program file after split is ensured to operate the same as the program file to be processed.

An apparatus for determining whether or not a program violates a convention, including an input unit for receiving an input of a target program to be an object of a determination on whether to violate the convention; a violation storing unit for beforehand storing any one of an abstract syntax tree and a pattern which indicate a structure of a program violating the convention; a converter for converting the abstract syntax tree of the target program to a conversion tree with a predetermined conversion rule; and a determination unit for determining that the target program violates the convention on condition that at least a part of the conversion tree agrees with an abstract syntax tree violating the convention.

Method to find a violation of a coding rule in program

A technique is provided for automatically and visually generating a display rule for a structured document based on an exemplary operation. Base display rule generation meansgenerates a first display rule, which is a base, by using a document type definitionfor a structured documentand a default generation rulethat is determined in advance. Display document generation meansemploys the first display ruleand the structured documentto generate a first display documentand an element correlation file. Tie first display documentis edited in a display document visual editing environment, and a second display documentand an editing operation history fileare generated. Display rule updating meansrefers to the second display document, the editing operation history file, the element correlation fileand the structured documentto generate a second display rulethat reflects the editing contents.

Method, system for, and program product for generating a display rule for a structured document, and for changing a structured document and its document type definition

A system is provided for preparing multiple recovery devices in accordance with the types of tokens in data strings, such as in programs or in documents, and the types of syntax rule errors, and for selectively employing recovery devices to correct errors. A structure recovery system comprises: a parserfor analyzing the structure of a data string written in accordance with a predetermined rule and for detecting an error in accordance with the predetermined rule; and a recovery device, independent of the parser, for, upon the receipt of a request from the parser, correcting in accordance with the predetermined rule the error detected in the data string by the parser, wherein the recovery device includes a set of syntax recovery unitsthat individually employ simple functions for correcting specific types of errors, and wherein the recovery device selectively employs the syntax recovery unitsin accordance with the error type according to the predetermined rule, in order to correct a variety of errors in a data string.
